It is narrated from Sayyiduna Marthad bin Abi Marthad al-Ghanawi (may Allah be pleased with him), who was a Companion who fought at Badr, that the Messenger of Allah (peace and blessings be upon him) said: "If it pleases you that your prayers be accepted (in the court of Allah), then let the best among you lead you in prayer, for they are your delegation (representatives) between you and your Lord, the Mighty and Majestic." Mention of Jabir bin Abdullah bin Ri'ab bin al-Nu'man bin Sinan:

It is narrated from Sayyiduna Urwah bin al-Zubayr (may Allah be pleased with him) that Sayyiduna Jabir bin Abdullah bin Ri'ab (may Allah be pleased with him), of Banu Salimah, took part in the Battle of Badr with the Messenger of Allah (peace and blessings be upon him).

It is narrated from Sayyiduna Jabir bin Abdullah bin Ri'ab al-Ansari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said, concerning this statement of Allah Almighty, "Allah erases what He wills and confirms (what He wills)" [Surah al-Ra'd: 39] , that Allah Almighty erases from provision (whatever He wills) and increases (whatever He wills).

It is narrated from Sayyiduna Urwah bin al-Zubayr (may Allah be pleased with him), in the list of names of the Companions who took part in the Battle of Badr with the Messenger of Allah (peace and blessings be upon him), that among them was Sayyiduna Jabbar bin Sakhr bin Umayyah bin Khansa' bin Sinan (may Allah be pleased with him).
